First Claim
1. A portable universal serial bus (USB) storage device, comprising:
- a core unit having a USB plug connector coupled to one or more multi-level cell (MLC) flash memory devices and an MLC flash controller disposed therein, the MLC flash controller controlling the one or more MLC flash memory devices and the USB plug connector providing an interface for accessing the one or more MLC flash memory devices;
a housing having a top housing and a bottom housing for enclosing the MLC flash memory devices and the MLC flash controller of the core unit, wherein the top housing and the bottom housing when attached together form a frontend opening to allow the USB plug connector to be exposed externally to the housing, wherein each of the top housing and button housing further includes a rivet opening at a backend of the top and bottom housings; and
a swivel cap having a top surface and a bottom surface by bending a flat panel into a U-shape block having an opening end, a close end, and at least one side- opening, wherein the top and bottom surfaces of the swivel cap include a rivet opening align with each other,wherein the housing having the core unit therein is sandwiched by the swivel cap using a set of rivets through the rivet openings of the housings and the swivel cap, wherein the core unit having the USB plug connector and the MLC controller and memory devices enclosed by the housing can be rotated with respect to the rivet set in and out of the swivel cap, and wherein when the core unit is swiveled into the swivel cap, the core unit is locked in a retracted position from which the core unit can be deployed by pressing from a side-opening of the swivel cap to unlock the core unit from the swivel cap.
